Definitions

  • the invention is directed on a decoupling device for actuators.
  • tangential rotary oscillations are produced, for example in a main excitation oscillation direction of the actuator, and oscillations are produced in the radial and axial directions.
  • tangential rotary oscillations are produced, for example in a main excitation oscillation direction of the actuator, and oscillations are produced in the radial and axial directions.
  • Decoupling devices for actuators and electric motors are known, but these are relatively rigid. Running noise of the electric motor and running-induced oscillations of a fan connected for example to the electric motor, e.g. due to an imbalance of the impeller, are largely transmitted to a fan housing and lead to an undesirable generation of noise.
  • the decoupling elements are adjusted in terms of their natural frequency so that a natural frequency of the decoupling element differs significantly from a natural frequency of the actuator.
  • the damping can as a result be partially increased.
  • EP 0 682 396 A2 has disclosed the use of elastic balls, preferably comprised of an elastomer, in order to decouple two components from each other.
  • the balls are each accommodated in an ellipsoidal cavity so that the balls permit a certain amount of free rotational movement.
  • Each component has cavities of this kind so that the cavities of the two components are disposed opposite each other after assembly. The cavities are let into an intermediary piece.
  • the device requires a central securing element and for damping, requires another elastic element which is disposed around a longitudinal axis.
  • the decoupling device according to the invention has the advantage over the prior art that an almost ideal decoupling of all oscillations of the actuator is achieved in a simple manner.
  • decoupling elements is advantageously embodied in the form of an “angular ball bearing”, since as a result, powerful forces can be absorbed and oscillations in the tangential direction can be damped. Oscillations in the radial and axial directions are damped through elastic compression of the balls.
  • the decoupling elements are simply subjected to pressure in all of the loading directions of the system. This results in a favorable ability to withstand vibration.
  • Particularly advantageous decoupling elements are rolling bodies in the form of balls made of an elastomer, which are connected to one another by means of an intermediary piece that is inserted into a slot of a securing element. This allows the decoupling elements to be very easily held and installed.

  • FIG. 1 shows a section through a decoupling device 1 with an actuator 2 .
  • This combination of the decoupling device 1 and actuator 2 for example an electric motor 2 , has a longitudinal axis 3 .
  • the decoupling device 1 is comprised of a decoupling housing 6 , which is composed, for example, of two annular parts, an upper part 7 , and a base part 8 .
  • the decoupling housing 6 is adjoined by a function housing 13 , for example a fan housing 13 , which encompasses a fan 12 driven by the electric motor.
  • the base part 8 of the decoupling housing 6 can, for example, also be part of the function housing 13 .
  • the decoupling housing 6 is then comprised of the housing parts 7 and 13 .
  • the decoupling device 1 is also composed of elastic decoupling elements 14 , 15 and a securing element 19 , e.g. in the form of a ring in this instance.
  • the decoupling elements 14 , 15 are for example rolling bodies which in this instance are embodied in the shape of balls and are made, for example, of an elastomer.
  • the decoupling elements 14 , 15 in this instance are disposed one above the other in pairs, for example, along a line 18 which extends parallel to the longitudinal axis 3 .
  • the actuator 2 is connected at least indirectly to the securing element 19 .
  • the decoupling elements 14 , 15 are connected to each other, for example, by means of an intermediary piece 20 .
  • a longitudinal axis of the intermediary piece 20 extending parallel to the line 18 runs parallel to the longitudinal axis 3 when the decoupling device 1 is installed.
  • the presence of the intermediary piece or strut 20 permits the two decoupling elements 14 , 15 to be very easily held simultaneously and permits them to be installed as an ensemble with the securing element 19 .
  • both decoupling housing halves 7 , 8 there are recesses 23 that open toward the longitudinal axis 3 and are disposed in the outer radial edge region, which constitute support shoulders 24 , 25 in the top part 7 or bottom part 8 of the decoupling housing for the decoupling elements 14 , 15 .
  • the securing element 19 disposed inside the decoupling housing 6 , 7 , 8 provides support shoulders 26 disposed opposite from the support shoulders 24 , 25 .
  • the support shoulders 24 - 26 have sections which are disposed in the radial direction and are referred to as radial support shoulders 24 . 2 , 25 . 2 , 26 . 2 . These are engaged by axial forces.
  • the support shoulders 24 - 26 also have sections which are disposed in the axial direction and are referred to as axial support shoulders 24 . 1 , 25 . 1 , 26 . 1 . These are acted on by radial forces.
  • Axial support shoulders 24 . 1 , 25 . 1 , 26 . 1 and radial support shoulders 24 . 2 , 25 . 2 , 26 . 2 are disposed for example perpendicular to each other here.
  • the support shoulder 24 . 1 is referred to as the axial support shoulder because it extends approximately parallel to the longitudinal axis 3 .
  • the support shoulder 24 . 2 is referred to as the radial support shoulder because in this instance, it extends approximately perpendicular to the longitudinal axis 3 .
  • the decoupling elements 14 , 15 are secured in the recesses 23 ( FIG. 7 ) and are connected to each other by means of the intermediary piece 20 , it is not possible for the securing element 19 to rotate entirely around the longitudinal axis 3 .
  • the support shoulders 24 - 26 are embodied so that when there is a relative rotation of the securing element 19 in relation to the decoupling housing 6 , 7 , 8 the decoupling elements 14 , 15 roll around a rotational axis 27 that extends obliquely in relation to the longitudinal axis 3 . In principle, this corresponds to the disposition of a dual-row angular ball bearing. In order to absorb axial forces in both directions, the decoupling elements 14 , 15 are disposed in opposition. Ball bearing terminology refers to X configurations and O configurations.
  • FIG. 2 shows the oscillation directions in the axial 30 , radial 31 , and tangential 32 direction, which occur during operation of the actuator 2 .
  • the decoupling device 1 should decouple these oscillations of the actuator 2 from the fan housing 13 , for example.
  • FIG. 3 shows how two decoupling elements 14 , 15 , which are round in cross section for example, are connected to each other by means of the intermediary piece 20 , for example.
  • the cross section of the intermediary piece 20 perpendicular to the line 18 can be rectangular or also round, for example.
  • FIG. 4 shows the top part 7 of the decoupling housing 6 from FIG. 1 in a bottom view and top view ( FIGS. 4 a, c ) and shows a cross section in FIG. 4 b.
  • the top part 7 has a round, annular cross-sectional contour. Any other cross-sectional contour is also conceivable, for example a quadriform cross-sectional contour.
  • the top part 7 can also be embodied as cup-shaped 33 , as indicated with dashed lines in FIG. 4 b .
  • the top part 7 contains for example three recesses 23 , which constitute the support shoulders 24 . 1 , 24 . 2 for the decoupling elements 14 .
  • center lines are shown extending from the recesses 23 , perpendicular to the longitudinal axis 3 that extends perpendicular to the plane of the drawing.
  • the drawing clearly shows that recesses 23 adjacent to one another in the circumference direction and decoupling elements 14 disposed in the recesses 23 are disposed at a uniform angle ⁇ from one another.
  • a section VII—VII in FIG. 1 is shown, which shows the recess 23 more clearly.
  • the decoupling elements 14 , 15 rest against the support shoulders 24 . 1 , 24 . 2 , 25 . 1 , 25 . 2 .
  • FIG. 4 b shows a plane 34 which extends perpendicular to the longitudinal axis 3 and passes through the radial support shoulder 24 . 2 .

  • the radial projection 35 is disposed, for example, on the outer edge of the securing element 19 .
  • This radial projection 35 can extend, for example, around the entire securing element 19 .
  • this radial projection can also be provided only where the decoupling elements 14 , 15 are disposed after assembly, which positions are indicated here with dashed lines, in order to separate the decoupling elements 14 from the decoupling elements 15 at these locations.
  • the securing element 19 is provided with a slot 36 in the projection 35 , into which the intermediary piece 20 is inserted. This facilitates assembly.

  • decoupling elements 14 , 15 are installed individually, without being connected to one another by an intermediary piece 20 , then instead of the slot, a recess 45 or an axial hole 45 can be provided, in which the decoupling element 14 , 15 is partially disposed so that is not possible to rotate the securing element 19 entirely around the longitudinal axis 3 .
  • the recesses 45 for example holes 45 , in the securing element 19 are produced, for example, so that after assembly of the decoupling housing 6 and securing element 19 , these holes are disposed centrally between the decoupling elements 14 , 15 .
  • the decoupling elements 14 shown with dashed lines here, are then disposed in the holes 45 .
  • a diameter of the holes 45 should not be so large that the axially opposed decoupling elements 14 , 15 touch after assembly.
